PRINTING-MACHINE.

SPECIFICATION forming' part'of Letters Patent No. 640,634, dated January 2, 1900. Application filed November 28, 1899. Serial No. 73 8,517. (No model.)

To (0% whom it may concern:

Be it known that I, JOHNSON Ross CORBIN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Printing-Machines, of which the following is a specification.

My invention relates to printing-machines, more particularly of the rotary type, and has for its objects to provide certain novel embodiments in the construction and operation of the same, more particularly relating to multicolor-printing in connection with the production of newspapers and magazines, as will be hereinafter more definitely set forth, and embraced in the claims appended hereto.

In an application for Letters Patent filed by me March 7, 1899, Serial No. 708,129, I have disclosed a novel apparatus for assembling a plurality of colors in predetermined spots upon yielding planographic transfersurfaces preparatory to taking multicolor impressions therefrom at a single imprint; and my present invention is specifically designed to utilize said broad idea in the production of multicolor newspapersheets or magazinepages in which one side of the sheet or page will first receive the usual impression of reading matter in one-colored ink from a suitable stereotype or electrotype form to be followed by a multicolor imprint upon the reverse side of said sheet or page and in substantially accurate register with the first imprint, said multicolor imprint being imparted at a sin gle impression and in as many as twelve distinct colors, if so desired, the said multicolor design being subsequently completed by imparting thereto the final print from what is termed the key-plate. To accomplish this result and obtain an imprint of as many as twelve colors is specifically the object of my present invention, and this I accomplish by employing two large cylinders rotating in unison, each carrying a plurality of yielding planographic transfer-surfaces, upon which are assembled inks in six distinct colors in predetermined spots, an intermediate transfer-cylinder being providedifor each large cylinder upon which said transfer-surfaces successively transfer their inks, said intermediate transfer-cylinders then transferring the inks to a single-design surface on the printing-cylinder, from which the imprint is made to the paper, each single combined transfer from the two intermediate transfer-cylinders constituting a complete inking for a single impression.

In the drawing accompanying this specification the figure is a side elevation of a rotary printing-machine embodying my improved construction.

In the said drawing the reference-numeral 1 denotes the frame of the machine, in which are mounted two cylinders 2, identical in size and construction, each of which is adapted to carry on its periphery a plurality of adjust able yielding planographic surfaces 3, preferably six in number, for each cylinder, the same constituting ink-transferring surfaces. Power is applied to the shaft of one of said cylinders to rotate the same, intermediate gear-wheel 4 imparting a simultaneous rotation to the other cylinder.

A series of cylinders 5, carrying what I term pattern-design forms, is provided for each cylinder 2, preferably six in number, each pattern-design form receiving its ink from an independent inking-train 6,as shown.

Mounted in proximity to each other are two cylinders 7, each carrying a yielding planographic transfer-surface that contacts with the surfaces 3 on one of the cylinders 2, said cylinders 7 contacting with a common printingcylinder 8, carrying a suitable form. Above said cylinder Sis the usual impressioncy'linder 9, while above the latter is a similar impression-cylinder 10, geared thereto by intermediate gear 11, as shown, a suitable printing-cylinder l2 completing the printing-couple for cylinder 10 and receiving its ink-supply from inking-train 13.

Above one of the cylinders 2 is located a printing-couple consisting of impression-cylinder 14 and printing-cylinder 15, the latter receiving its supply of ink from inking-train 16 in the usual manner, said printing-couple being geared to rotate in unison with the rest of the machine by means of gear 17 in mesh with one of the pattern form-cylinders 5, as shown.

W'hen employed in printing from a Web, as when printing both sides of a newspaper-sheet or a magazine-page, the web 1b is first led between printing-couple 14 15, where it receives an ink impression on one side of the sheet, the form on cylinder imparting, for instance, reading matter only. The Web then passes between printing-couple 8 9, Where it receives an impression from cylinder 8 on the reverse side of the sheet, this impression being made up in the following manner: The design to be printed on this side of the Web is produced in relief on the plate carried by cylinder 8, while the surfaces of the pattern-design forms on cylinders 5 have been previously prepared in a predetermined pattern design, so that each pattern-design form will receive its particular colored ink from its inking-train 6 and deposit the same on each yielding surface 3 as it passes in contact therewith, the patterndesign forms being so arranged that each surface 3 will receive the different inks accurately in predetermined patches and will in succession deposit said inkings on the transfer-surface of its cylinder 7, the said transfersurfaces then depositing the inkings onto the plate or form on cylinder 8, each single combined transfer of cylinders 7 constituting a complete inking fora single impression from said plate or form. It will thus be seen that with six cylinders 5 and six transfer-surfaces 3 for each cylinder 2 twelve different colors may be imparted to the plate or form on printin g-cylinder 8, said twelve colors being simultaneously printed upon the Web in its passage between the printing-couple 8 9. The web then passes between printing-couple 1O l2,the printing-cylinder 12 carrying What is termed in color-printin g the key-plate for the final printing in one color, preferably black,though said plate may also have thereon any reading or other matter that it is desired to print on this side of the Web. It will thus be seen that the web first receives the usual impression in one color on one side from printing-couple 14 15, then receives a complete multicolor print at a single impression from one plate on the reverse side of the Web from that imparted by printing-couple 8 9, and finally receives the key-plate impression to complete said multicolor print, as Well as any desired reading or other matter, from printing-couple 1O 12. It will he understood, however, that the form or plate carried by printing-cylinder 8 may be so prepared that the resultant multicolor impression from it will be a complete and finished product in itself, the use of the printingcouple 10 12 not being necessary in all cases for the production of a complete multicolor print, as it is frequently desirable for special purposes to produce a complete multicolor print from one plate With a single impression.

By employing a plurality of, say, six transfer-surfaces on each of cylinders 2 it will be seen that six separate and complete inkings will be imparted to the printing-cylinder 8 for each rotation of cylinders 2, While the use of a dilfe1entcolored ink in each inking-train 6 will impart to said cylinder 8 twelve distinct colors for each impression. It is sometimes desired, however, to ink certain colors more heavily than others, which may be accomplished by employing the same color in two or more of the trains 6, the pattern-design forms therefor being arranged to depositin the same spot or spots on surfaces 3, thus providing a double inking for said color for each impression. Thus, for instance, two colors may be inked twice and eight colors once or three colors twice an d six colors once. In fact, this feature may be varied at will to suit the requirements of the multicolor subject,the portions Where a small quantity of ink will suffice receiving but a single inking, while those portions requiring a greater quantity of ink may receive additional inkings by duplicating the pattern-design forms and colors.

While I have shown and described my machine as adapted more particularly for Webprinting, it will be understood that the same may be used for printing upon separate sheets, though in this event a suit-able feedboard, grippers, tapes, 650., will be required, as is well understood in the printing art.
